UNITED STATES PATENT OFFICE- SUSAN E. FOX, OF PARIS, TENNESSEE DISPENSING CLOSURE FOR CONTAINERS Substitution for abandoned application Serial No. 65,543, filed. December 7, 1915. This application filed February 12, 1930.

' 5 application filed December 7, 1915, Serial Ordinarily, such tubes are provided with closures which are removable and which are consequently liable to be lost or misplaced, or

where such closures are so constructed as to be capable of manipulation to permit the discharge of the contents of the tube and yet remain permanently connected with the discharge "spout, they usually require manipulation by one hand while the tube is held in the other hand, which is inconvenient.

The invention has for its primary object,

therefore, to provide a closure which will effectually prevent the evaporation or caking of the contents of the tube and which may yet be readily manipulated by thethumb of the hand in which the tube is grasped to permit the discharge of the contents of the tubeor to close the outlet opening from the spout in Figures 2 and 3 of the drawings. It will of the tube.

Another object of the invention is, to provide a device of this character having means to cut oif the supply of paste so that the tube may be laid upon any convenient supporting surface without likelihood of the contents being contaminated. F v Afurther object of the invention is to provide a novel *means for locking the closure.

in closed position, which means, however, will not interfere with the intentional swinging of the closure to open position.

Still further objects of the inventionnot specifically mentionedv in the following will appear during the course of the following description.

In the drawings: Figure 1 is a perspective view illustrating the manner in which the device is to be employed.

Figure 2 is a vertical longitudinal sectiona1 bgiew through the. discharge 'end of the tu L Figure 3 is a horizontal sectional view on the line 3-3 of Figure 2, looking in the di- 50 rection indicated by the arrows.

solid substantially frusto-pyramidal bod of suitable dimensions having relatively incllned rear'and forwardsides 3 and 4 respectively,

and relatively inclined lateral faces 5, the

facesv 5 being inclined, not only in an upward direction toward each other, but lying also in planes converging in the direction of the forward faced of said body. The body 2 is provided with a passage 6 which communicates with the interior of the tube 1 through the under side of the body and which opens through the forward face 4 of the body, the

passage being gradually restricted in the direction of its open end, as clearly illustrated now e apparent that when the tube 1 is pressed, the paste within the tube will be forced outwardly through the passage 6, issuing in a ribbonlike stream through the open end of said passage, as illustrated in Figure 1 of the drawings, and in such manner'that the paste may be laid alongthe bristles of a tooth rush.

The closure for the spout above described comprises sides 7 which are inclined and which lie in converging planes so as to snugly embrace the lateral faces 5 of the body of the spout when the closureis in closed position,

a top 8 which is arranged to rest upon the corner thereof and is pivotally engaged at itsends in the side walls 7 of said closure, or, if desired, the closure may be similarly connected in any other suitable manner. In order that the closure may be conveniently swung from open to closed position, and vice versa, a lip 11 is provided at the rear edge of the top 8 of the closure and may be engaged by the thumb of the hand in which the tube is grasped, in the manner clearly shown in Figure 1 of the drawings. At the Junction of'the side walls 7 of the closure with the forward wall 9 thereof, said side walls are struck outwardly as indicated at 12, to form channels 13 receiving the edges of a lining 14: of cork or any other suitable material, which lining covers the inner face of said wall 9, as shown in Figures 2 and 3 of the drawings. and is designed to close the discharge end of the passage 6 in an air-tight manner. In order that the discharge end of the passage may be completely closed, the forward wall 9 of said closure is provided with an elongated longitudinally extending indentation 15 resultin in a correspondingly shaped rib 16 which bulges the intermediate portion of the lining 14 in the manner indicated at the numeral 17, so that, when the closure is swung down to closed position, tl1is bulged portion of the lining will seat within the discharge end of the passage. I

In order that the closure may be locked in closed position, the side faces 5 of the spout 2 are provided each with an indentation 18 adapted to receive a protuberance 19 formed by indenting the corresponding wall 7 of the closure, said closure being formed from resilient metal so that as it is swung to closed position, the protuberance 19 will spring into the indentations 18. In order that the closing movement of the closure may not be interfered with, a groove 20, shallower thanthe indentations 18, is formed in each side face of the spout 2 concentric to the pivot for the closure and communicating at its lower end with the respective indentation and at its upper end terminating at the top of the face of'the body in which it is formed. As

an additional means for locking the closure in closed position, the lower edge of the front wall 9 of the closure is provided with a flange 21 designed to ride over the lower portion of the forward face 4 of the body 2 and spring into'engagement with a transverse seating groove 22 formed in the faceA at the bottom thereof. The engagement of this flange 21 in the groove 22 serves also as an additional means for preventing the entrance of air} or moisture into the passage 6 and also prevents leakage of the paste in the event that the cork lining becomes worn.

What is claimed is: V

1. A container including a body portion having a. substantially frusto-pyramidal spout extending longitudinally from one end thereof and provided with, a discharge pas-.

sage opening through one end wall of the spout, a closure corresponding in shape to the spout and pivotally mounted thereon and having an inwardly bulged portion adapted to fit within the mouth of the discharge passage when the closure is in closed position, the ends of the side walls of the closure on opposite sides of the bulged portion being bent to form channels, and a packing strip seated in said channels and extending over the bulged portion of the closure.

2. A device of the class described comprising a compressible container having a solid substantially frusto-pyramidal discharge spout projecting longitudinally from one end thereof and having alaterally and downwardly inclined Wall, there being a discharge opening formed in the spout and having one end thereof communicating with the interior of the container near the center thereof and its other end opening through the inclined wall of the spout near the center thereof, a closure conforming to and pivotally mounted on the spout and having an inclined end wall, a lining member carried by the inclined end wall of the closure and adapted to project within the mouth of the discharge passage when the closure is in closed position, a finger piece carried by the pivoted end of the closure, and interengaging locking means formed on the spout and closure respectively.

3.v A device of the class described comprising a compressible tube having a solid substantially frusto-pyramidal discharge spout projecting longitudinally from one end thereof and provided with a downwardly and laterally inclined end wall and side walls con-h verging in the direction of said end wall, said spout being formed with a discharge passage, the mouth of which is constricted and opens through the inclined end wall of the spout, and a closure pivotally-mounted on the spout and having an inclined end wall coacting with the inclined end wall of the spout, the inner face of the inclined end wall of the closure being adapted to project within the constructed mouth of the discharge passage when the closure is in closed position.

In testimony whereof I afiix my signature.
